Abstract: In an embodiment, an amplifier circuit includes a second stage (322) that includes a first switch circuit (330) including first and second terminals, a plurality of resistive elements (340, 350) coupled between the first and second terminals of the first switch circuit, and a plurality of switches (342, 352) configured to control an equivalent resistance between the first and second terminals of the first switch circuit. During play mode, the second stage (322) has a gain between the input of the second stage and the output of the second stage of a first value. During a transition from mute mode to play mode, the amplifier circuit is configured to progressively increase the gain of the second stage (322) from a second value to the first value. During a transition from play mode to mute mode, the amplifier circuit is configured to progressively decrease the gain of the second stage (322) from the first value to the second value.

Abstract: A process is provided for regenerating a spent electroless copper plating bath which contains alkali metal salts resulting from the reduction of a water soluble copper salt under copper plating and reducing conditions. The regeneration is effected by means of the electrodialytic transfer of at least a portion of the anions in the spent plating bath through an anionic permselective membrane (18) into the anode compartment (12) of an electrodialytic cell (10). In the preferred embodiment, hydroxyl ions from the cathode compartment (16) of the electrodialytic cell (10) are concurrently transferred through a second anionic permselective membrane (20) to replace the transferred anions, the replacement taking place in a compartment (14) of the electrodialytic cell (10) located between the two anionic permselective membranes (18,20). E.g., the spent solution to be regenerated is an aqueous solution containing Cu ++ , Na + , OH-, HCOO-, SO 4 --, HCHO and the sodium salt of EDTA.

Abstract: In a sodium sulphur cell, having a cathode structure 15 (Figure 1) between a cathode current collector 14 and a solid electrolyte 10, the cathode structure is formed of a fibre material with at least 90% of mesophase-pitch-based carbon fibre material with the fibres oriented in two dimensions parallel to the plane of a mat, the mat then being needle-punched to re-align fibres and so increase the electrical conductivity transverse to the plane of the mat. Preferably up to 10% of a material having a greater resistance to bending is incorporated before needling; these may be carbon fibres which are non-mesophase-pitch-based. Alumina or other electrically non-conductive fibres may alternatively or additionally be incorporated. These further fibres can be chosen to improve the resilience of the cathode structure. The mat is impregnated with the cathodic reactant, i.e. sulphur or sodium polysulphides, in liquid form and' cooled while compressed to solidify the reactant and form a rigid unit for insertion in the cell, which unit will expand when the reactant is liquified at the operating temperature.

Abstract: The invention relates to a circuit for varying the light intensity of fluorescent lamps and its use. Figure 5 shows a fluorescent lamp (1), a four-pole network (4) and an electrical circuit (23). The four-pole network (4) can be designed for use on d.c. or a.c. voltage mains. The circuit (23) shown is used for twilight control and day-length control in plant and animal husbandry. By means of another version of the circuit (23) the circuit can be used for room, tunnel, exterior, display window or vehicle illumination as well as for advertising and entertainment purposes. The version of the four-pole network (4) shown ensures reliable ignition conditions for normal fluorescent lamps without ignition strips or other means of assistance to the lamp fittings. The twilight ratio is very high and corresponds to the practical requirements. By avoiding phase-chopping and higher frequencies, the generation of radio interference is minimal. The exclusive use of mass-produced components ensures economical production. <IMAGE>
